I agree with all the previous comments and like Karen, prefer a 2-piece wetsuit. It’s more versatile because you can wear it with long or short pants depending on the conditions.
Another reason is that I find it more comfortable, because I have along torso and feel compressed in a farmer Jane suit. But the most important reason for me is that the 2-piece suit is easier and more comfortable to deal with when going to the bathroom out in the bush. Especially on a colder or rainy day stripping out of a farmer Jane suit can be very awkward and cold.
